But when Fretwell looked at the satellite pictures, he saw few signs of the birds.
Where we diverged: WebVideoCreator was built against the old headless mode on the main chrome binary. Since then, Chrome split the old headless mode into a separate chrome-headless-shell binary with a different API surface (starting with Chrome 120, fully removed from the main binary in Chrome 132). We also needed tighter integration with our cloud infrastructure (Cloud Run, GCS uploads, Datadog tracing), stricter security (SSRF protection for rendering untrusted URLs), and more control over the video element pipeline and audio extraction. So we rewrote it in TypeScript with modern Puppeteer and adapted the architecture for our deployment model.

At this point, each bound sequence exists as a single copy, which produces too faint a signal to detect reliably. Colony sequencing solves this by generating clusters of identical fragments through a process called bridge amplification. The adapter on the free end of each DNA strand will be complementary to some of the original, short sequences on the DNA lawn, and when this binding occurs, the strand bends over to form a bridge shape. Another round of amplification takes place, resulting in two complementary strands each directly affixed to the flow cell. This “bridge amplification” process is repeated over and over to propagate the sequence.
The matrix on the left is called the Vandermonde matrix. This matrix
